Abstract
This study aims to describe in detail the results of the development of a problem-solving STEM module with the theme of the dome house, and explain the results of the improvement after the use of the module. STEM is an approach that combines science, technology, engineering, and mathematics into a single discipline that is able to realize learning by presenting real problems in everyday life. The STEM module based on the problem-solving ability developed raised the theme of the dome house, which has a function as an earthquake-resistant house which was used as a reconstruction of post-earthquake housing and is permanent, economical, and efficient. Solving problems is one part of high-level thinking, as well as a form of action in solving problems that utilize the knowledge they have. Indicator of achievement of problem solving is analyzing the problem, making a plan for its completion, carrying out planning, and checking again. The development method applied is Research and Development. This module is validated by 5 experts, the results show that the module is very feasible to use. The module was tested on research subjects totaling 20 eighth grade students. The results show that the highest increase in students' problem-solving ability after the implementation of the module is the indicator carrying out the plan with n-gain 0.40, while the lowest increase in the indicator understands the problem with n-gain 0.22. Overall, the STEM module that was developed was able to improve the problem solving ability of state Islamic junior high school students.

Summary
Modul STEM pada rumah dome berbasis memecahkan masalah ini dikembangkan dengan model ADDIE (Analysis, Design, Development, Implementation and Evaluation). Berikut adalah proses pengintegrasikan STEM pada rumah dome dalam modul yang disesuaikan dengan materi getaran, gelombang dan bunyi dapat dilihat pada Gambar 1. Sedangkan jika ditinjau dari sisi engineering, design/ rancangan pembuatan rumah dome (tahan gempa), bahan pembuatan, serta cara membuatnya. Jika ditinjau dari sisi sains Getaran dan gelombang yang menyebabkan terjadinya gempa bumi sehingga dibutuhkan rumah tahan gempa dimana airfoam dijadikan sebagai bahan pencetaknya serta persamaan frekuensi dan periode pada getaran dan gelombang seismik. Jika ditinjau sistem pondasi dari rumah dome dibuat sedemikian rupa dengan melingkar sehingga akan memberikan ketahanan merata pada semua bagian bangunan. Hal ini tidak lepas dari implementasi sains dalam rumah dome yang dibuat dengan memperhitungkan implementasi dari persamaaan cepat rambat gelombang serta mampu menahan kecepatan hembusan angin hingga 450 km/jam. Peningkatan kemampuan memecahkan masalah terlihat seperti pada Gambar 2
